“…The corn fiber-based adsorbents, [57] which are ecologically friendly, have been applied in the adsorption of cationic dyes and effluent contaminants including alcian blue, methylene blue, and neutral red. For this, minimal chemical modification is required, for instance, washing with sodium hydroxide solution and isopropyl to remove pig- Ni 2+ 2.1 [45] Water hyacinth Pb 2+ 95.5 [45] Ni 2+ 7.4 [45] Cashew nutshell Cr 3+ 84.2 [48] Pb 2+ 28.6 [48] Cd 2+ 11.2 [45] Chestnut bur Pb 2+ 74.35 [49] Cd 2+ 34.7 [49] Peanut shell Pb 2+ 38.9 [50] Cr(VI) 4.3 [51] Pinecone shell Pb 2+ 17.4 [52] Cu 2+ 6.5 [52] Eucalyptus bark Pb 2+ 20.7 [45] Ni 2+ 3.2 [45] Piassava Pb 2+ 5.0 [45] Ni 2+ 1.49 [45] Raw rice Pb 2+ 42.6 [53] Eucalyptus camaldulensis Se 41.8 [54] Ficus auriculata leaves powder Cr(VI) 13.3 [55] Watermelon shell Cu 2+ 9.5 [46] Lemon peel Cu 2+ 8.2 [46] Sorghum powder Cu 2+ 7.9 [56] Banana powder Cu 2+ 6.5 [56] Casuarinas powder Cu 2+ 4.5 [56] Amaltas leaves Cr(VI) 4.5 [51] Indian Jujube sawdust Cr(VI) 3.6 [51] ments, low molecular weight species, and organic species such as polyphenols.…”

The use of unmodified and chemically treated natural fibers for water remediation (removal of chemical residues/oil spills and organic wastewater from water) is a significant and low-cost strategy to reduce the contamination of aquifers with metal ions, as well as marine environments with oil spills and water bodies with organic dyes. Furthermore, synthetic fibers exhibit a superior performance owing to their tunable surface area and superhydrophobic/swelling properties. This review summarizes the most recent advances in natural fiber-based biosorbents and synthetic fiber mats since the efficient removal of toxic compounds depend on adequate incorporation of functional groups on the fiber surface for mutual electrostatic and diffusion of contaminants into the fibrils. The most relevant results in the removal of oil, trace metal ions, and organic dyes are presented and evaluated. The evaluation is done according to the strategies for chemical modification of raw materials by the reuse of plastics or conventional electrospinning techniques to support the hierarchical growth of more complex chemical structures.

“…The data indicate that percentage of dye removed decreases with increase in the initial concentration of dye. As at lower concentration, maximum dye particles in solution occupy available binding sites on adsorbent, which results in better adsorption [38]. But at higher concentration, the available sites on the adsorbent become limited and there is no further adsorption.…”

The present investigation describes the conversion of waste product into effective adsorbent and its application for the treatment of wastewater, i.e., chemically modified solid waste from paper industry has been tested for its adsorption ability for the successful removal of Rhodamine B dye from its aqueous solution. The adsorption isotherm, kinetics and thermodynamic parameters of process have been determined by monitoring the different parameters, such as effect of pH, amount of adsorbent dose, concentration, contact time and temperature. The equilibrium data has been well described on the basis of various adsorption isotherms, namely Langmuir, Freundlich and Temkin adsorption isotherm. From Langmuir isotherm, the maximum monolayer adsorption capacity has been found to be 6.711 mg g-1 at 308 K temperature. The kinetics of adsorption has been studied using pseudo-first order, pseudo-second order and intra-particle diffusion model and the results show that kinetics has been well described by pseudo-second order. Thermodynamic parameters, such as free energy change (DG), enthalpy change (DH) and entropy change (DS), have been evaluated. The free energy has been obtained as-11.9452 kJ mol-1 for 75 mg L-1 concentration at 308 K temperature. Desorption and recycling efficiency of adsorbent has been studied and the adsorbent shows good recycling efficiency.
